few questions
-are you using a wide band 02 for tuning
-what are you using for "target" a/f at cruise/spool(below 5 psi)/above 5 psi
-do you have any sort of knock sensor
-what spark plug are you using?
- did you have to change the crank pick up between the ej20g (old engine which was 200,220 or 265ps not 165hp) and the new ej207
- did you rescale the injectors from [email protected] with the old engine to [email protected] bar for the new?
- what size of map sensor came with the stinger 2 or 3 bar?

sidenote - there is probably a market for the unused harness and ecu from the 207

I have had the car running for about a month now, and boy is it fun!!!

I do have a few quesitons, I have a bit of an oil leak and want to verify that both of these ports off the block are infact case vents... Please let me know. I know the previous EJ20 that I had did not have the one closest to the center of the engine. Where do these go in a factory application?

extremely bad ass setup, I am not sure about that crossover pipe port, if i am not mistaken..i think our usdm engines don't have that port..i will do some research and get back to you..

did someone tell you to get the oem bov(it's actually a by pass valve) or did you figure that out intuitively? if so, you are one smart man as the bov's aren't setup in 50/50 form, the usually vent 100% and don't recirculate back and that's why your ecu was tripping out

that center port is a direct vent for the crankcase but since you have the others you can just cap it off like everyone else does on hybrid builds.The port by the turbo is where the sti has the pcv connected to,the pcv is a plastic three port piece that is about 10.00 at the dealer.I hope this helps.^^^^he does not need to recirc the bov his stinger ecu is speed density --the maf is gone.

We last left off back a number of months ago, I drove the car 2hrs north to Effingham Il, on Sat evening after work. About an hour on the interstate, I had to pull over as I noticed that the car was slowly getting hotter. This told me alot about what is needed in the future regarding the cooling. I pulled over at a rest area and started playing with the Stinger on the laptop. For some reason, the fans weren't triggered to come on, so I changed the values and we were up and going again. I think the ambient temp was pushing 100°F that day.... None the less, I had previously installed some tempory "scoops" to direct the air flow from beneath the car up to the radiator. Considering that I was needing the fans to run down the interstate tells me that I am in need of possibly better ducting, larger radiator, or something I haven't thought of yet.

I continued up the road in time to meet up with a buddy that has a VW Buggy with an EJ20T and a bunch of other guys at a resturant. After talking vw's, subi swaps, our two cars specifically, I continued an additional 20miles north to stay the night with my friend at his house. Well, during this little trip, I sprung a leak in the radiator, but was able to make it. Unfortunately, one of the radiator fans rubbed/vibrated a hole in the cooling passage of the radiator, and was leaking tremendusly by the time I got to his house. Pic below is the antifreeze leaking on the exhaust.

I called around to all the parts stores trying to find a radiator out of a 6cy Jeep Cherokee (this is the rad. I am using) and ended up finding one. Due to the time of everything, later I replaced the radiator and drove 2.5hrs south home with no problems.

That very next day, the 2010 Hot Rod Power Tour came thru my area, only 20mins away in DuQuoin Ill, they said there were over 3000 cars on display. I headed up there that afternoon in the VW, showed the car, noticed from the distance spectators pointing to the engine compartment in disbeleaf

The Highlight - On my way home from the show, I was sitting at a stoplight on the outskirts of town (immediately turns to 55mph and not another stoplight, entrance or exit for 2miles) and up next to me rolls a 69 Camaro. Now let me tell you, this was one badass car! Silky smooth paint, lowered with larger rims and low profile tires, and I dont know for sure, but possibly a big block! It sounded everybit as good as it looked! Now my heart is racing, my palms are a bit sweaty, and I look over and rev the VW waiting for the green light. He looked back with a smile - probably thinkin what a joke! The funny thing was the joke was on him!!!! The light turned green, I let the clutch out aggressively but not side stepping it ( I still have the factory orginal 1968 VW Tranny) he had a bit better reaction time was just a bit ahead. I then immediately put the pedal to the floor, shifted to second and all of a sudden I am looking at his headlights out the passenger rear window, threw it into third and I couldn't believe it, I am now seeing his headlights decending in the rear view mirror, into fourth for a bit and decided that was it!!!! I am now in disbelief but yet also have the biggest smile on my face... It wasn't even close, I must have been every bit of 50ft ahead of him, yet right off the line, he was 3ft or so ahead of me... As I slow down, now cruising at 60ish mph he pulls up beside me, shakes his no and gives me a thumbs up. He then pulled off at the next light and went to the hotel as I continued on. I couldn't help but think, did he just get back to the hotel (parking lot was full of old cars) and tell his buddys what had just happened, or not say a word? Either way, its pretty funny! Who would ever think while driving a old hopped up Camero, that an old VW Bug would spank them.

That following week, My Father came to visit, and was anxious to go for a ride as I had told him this story and how well the car was running. We go for a small little ride, to get the engine up to temp, I pull out of my subdivision and romp on it, shift from 1st to 2nd and BANG!! there went the trans! It now has no forward or reverse gears. Due to how busy I have been, I pushed it into the garage where it has sat ever since. I am planning on getting a Rancho Trans this winter and replacing the tranny.. Its a never ending project!

At the rest area trying to figure out why the cooling fans aren't kicking on
Pulling into my buddies house, antifreeze driping on the exhaust

Dad and I pulling out, a few minutes later, the trans blew!!!

Nice project.
I am dropping an 05' sti powerplant into a 1969 VW BUG IRS chassis at the moment.
Running it through a fully built porsche 901 5spd in order to hopefully avoid what has fallen your poor car...

Your doing great work, stick to it.
Looking forward to hearing about it more.
Thanks for sharing.

My dad and I are considering the swap to either a 205 or 207. The current 1641 being rebuilt needs a few heli-coils installed, so it's time to tear down again. Does anyone know whether a 207 can be used with a 205 ecu and rewired harness? 205s in my area run steep, but an ecu / harness are relatively cheap. Just want a comparison with the cost of the Stinger eco 4.
